Referring tc the drawings, which illustrate a practical embodiment ofthe present invention,

I indicates a substantially rectangular base upon which are mountedVertical standards 2 2 pro# vided with suitable journals to receive amain ro- -5i tary shaft 4 v.extending longitudinally of the base.

A third vertical standard 3 is positioned on the base at one end insubstantial alignment with standards 2 2.

The shaft 4 at one end extends beyondthe nj adjacent pedestal 2 and hasmounted thereon a lfreely rotatable pulley 5 provided with an annularclutch flange 6 and secured on the shaft by suitable washers l and 8 bya collar 9 secured on the shaft by a set screw 9. A clutch member 15' I0is slidably mounted on shaft 4 as by feather II between the adjacentpedestal and pulley 5. The clutch member -Ill is provided with aplurality of radial fingers I2 adapted to engage the annular clutchiiange 6 of pulley 5' and the' 420 clutch is provided with a peripheralgroove I3 in which isfpositionedfring I4 secured to clutch lever I5which is pivotallysecured to the base as by screw I6. A resilient arm I1is rigidly secured to the base as by screw I8' and its upper r5,35

end engages the hub of clutch I0 so as to `damp the rotation of theclutch upon the release of the clutch. A collar I9 is xedly secured toshaft 4 as by set screw 20, to secure the clutch j and pulley assemblywith respect to the adjacent '30 pedestal 2.

Onthe opposite end of the main shaft 4 is slidably mounted a sleeve 2|having at its ends peripheral ilanges 22 and' 23. -A ring 21 surroundssleeve 2I being associated with arm 28 35 which terminates in akthreaded boss 29. The ring 27 is secured against axial movement onsleeve 2I by collar 24, secured on the sleeve as by set screw 25. l v

The threaded boss `29 of arm28 isthreadedly 40 mounted onthethreadedportion of a rod 30 which is slidably mounted parallel with mainshaft 4 in adjacent standards 2 and 3. 'Ihis rod 30 has on its inner endya` cam follower 36 and the boss 29 is provided with a set screw 3|, by45 means of which itsadjustment upon the threaded shaft 30 can besecured. A coiled spring 32 is positionecl'on the rod 30 betweenpedestal 3 and across pin 3| by means of which rod 30 is resilientlypressed in the direction of cam fol- 50 lower 36. The outer end of rod30 is provided with a threaded section upon which is mounted lock nuts34 and the rodis further provided with a knurled knob 35 by means ofWhich it can Y be adjusted. f Y N55 A resilient bumper 33 is positionedon rod 30 between lock nuts 34 and standard 3.

On the outer end of sleeve 2| a lug 31 is secured to flange 23 and thelower end of this lug projects into an axial slot 40 in the free end ofshaft 4. A hook engaging hood 4| having a hook engaging slot 42 with aninclined bottom 43 is adjustably secured to flange 23 by means of screwsV38 positioned in slotted flanges 39 which extend on opposite sides ofhood 4|.

The hook H as indicated by dotted lines in Figure is adapted to be.positioned with its shank in slot 40 and the hook part resiliently heldin the slot 42 of hood 4| by means of the inclined bottom 43 of saidslot. The entire sleeve 2| with its associated hood 4| is slidable uponshaft 4, and is rotated with the shaft by the engagement of lug 31 inthe slot 40.. Sliding of sleeve 2| upon shaft 4 will feed hook Houtwardly with respect to shaft 4 within the slot.

The shank of the hook H is held in shaft 4 near its outer end by a pin9D slidably mounted in the shaft transversely of slot 40. This pin 80has a rounded inner end and is resiliently pressed across slot 48 as byspring 9|.

. Positioned on base intermediate standards 2- 2 and in transversealignment with shaft 4 are two standards 5-50, upon which is mountedtransverse cam shaft 5| upon one end of which is mounted cam 52 securedas by set screw 53, which cam `is positioned to engage cam follower 36on the end of rod 30. Between standards 50-50 a worm gear 54 is freelymounted on cam shaft 5| and this worm gear 54 engages a worm 55 formedon shaft 4. The worm gear 54 is provided with an ilo posed dogs 66biased by springs 6|. secured to posts 52 against the gear teeth 51.Mounted on cam shaft 5| and also between standards 50-50 are two similarcam discs 68 and 65, one of which, 68, islfixedly secured to cam shaft5| as by set 4,5 screw 64 and the other, formed as an annular flange onsleeve 66, is rotatable with respect to shaft 5|. Both ofthe cam discs68 and 65 are formed with similar high and 1ow portions 66' and 61',which are semi-circumferential in extent so that by varying the angularadjustment of these two cam discs with respect to eath other therelative lengths of the effective high and .low cam portions of the twodiscs regarded as a common cam can be modified as desired. On the outerend of sleeve 66 isan annular flange 61 provided with a plurality ofspaced orifices 90 arranged circumferentially. On thek outer end of camshaft 5| is a disc 69 having a flange 16 and GO fixedly secured to shaft5| as by set screw 1|.

The disc 69 is provided with an orifice 12 threaded to receive a screw13 having a knurled head 14, which screw 13 is adapted to be selectivelyentered into one of the spaced orifices of flange 61 .6,5 by which meansit will be apparent that the ro- 13 will operate to rotate combined camdiscs 68--65 in unison, such rotation, however, being possible only inone direction by reason of the ratchet and dog connection between disc58 and worm wheel 54. The cam discs 68-65 are en- ..,5 gaged by a commoncam follower mounted on a rod 15 slidably supported in standard 2 andconnected to clutch lever I5 as `by pin 16.

In operation it will be observed that the rotation of disc or controlwheel 69 will rotate cam discs 68-65 from the inoperative position ofthe machine, in which cam follower 14 is set against the low camsurfaces and clutch ID is disengaged from pulley 5 tobring the yhigh cam`.surface in contact with'cam follower 14?' and thus engage clutchIlland start the rotation of shaft 4 which will continue until thefollower 14 again drops against the low cam surface. It will further beobserved that the relative lengths of the high and low cam surfaces canbe adjusted by means of the same control wheel 69 by adjusting sameannularly with respect to flange 61 thus modifying the angularrelationship of discs 68-65.

A pinA 18 mounted on the base is adapted to receive a spool S containingthe thread T for use with themachine and the spool S is damped by `meansof a coiledspring 19 secured againstvsame as by pin 80 passing throughpost 18. The thread T is extended from spool S through a guide coil 8|secured to the base and thence between hard polished washers 82 mountedon a post 83 secured to pedestal 3'by a bracket 81. 'Ihe tension of thewashers 62 is controlled by a compression spring 84, the force ofwhichis adjustable by means ofcottapin 85 and its selective insertion intoone of a plurality of holes 86 in rod 83. From washers 82 the thread isextended through a slot 88 in the bracket 81.

Theend of the thread is given a counterclockwise turn about the. shankof the hook and associated gut and then. passed under a tension linger45 secured in the end of shaft 4 and provided with afknifeedge 45',which can be used at the conclusion of the wrapping operation to severthe thread T, preliminary to a repeat operation.

In operation the fishl hook to be snelled is placed with its shank inslot 40 and with the hook caught under anvil 4l as indicated in Figure5. The thread T is carried from spool S through the guide 8| and betweenthe washers 82 and under the catch onthe end of the shaft. `A length ofgutor cord is then placed in slot 4l) over the hook shank.

Byturning disc 69 by hand spoke 11, shaft 5| is then rotated until thecam formedby the cornbined discs 65 and 68 engages roller 14 thus en-4gaging the main clutch Wand starting the inachine. The machinecontinues operation as long as that cam rides against roller 14, whichwill be determined by the size of the cani, which in turn, is determinedas previously pointed out by the angular relationship of cam discs 65andGB.

During the operation of the machine the cam 52 will bear againstfollower 313, thus propelling carriage 2| outwardly and providing forthe even spiralwinding of the threadfaround the superposed shank andgut.

As previously indicated, the drawingsherein represent a practicalembodiment of the invention but Various modifications will readilysuggest themselves to those skilled in the art but within the scope ofthe invention as claimed.
